Advice for choosing between elixir and nodejs

I have been lurking around here some days now and heard (read) lot of good about this community.

Now I could need some advice or a second opinion for choosing elixir for my personal projects. All my ideas are web related and some are in IoT world. So far I have used Angular6 for frontend, and nodeJs/typescript for backend REST service and I deploy with kubernetes.

Stack is mostly chosen based on tech that is used at work.

I just started developer career, I have background in QA/automation engineer, so I do not have much experience of writing big applications yet.

Im kind of between 2 choices NodeJs or elixir.
